I'm helping a fellow Forum member @PlyWoodsell his collection of '41-'54 Plymouth and Chrysler cars and parts because he is moving and has no room at the new digs. He has a newly rebuilt C54 256 cu in motor he's selling with a '40 Chrysler 3spd with factory OD. (See Classifieds) A great Forum post from 2015 "The Rough Field Spotters Guide for Mopar Overdrives" talks about the 1940 Chrysler OD as being a one year model where "the last year where the gear cluster and 2nd speed gear in the 3 speed transmission gave you a "fast 2nd speed". This was done with a cluster tooth count of - "14.19.25.32" and the 2nd speed gear was a 23 tooth count. After this the cluster was a tooth count of "14.19.23.32" In a recent post @Loren mentioned that my 1940 Plymouth transmission might also have a fast 2nd. Was this a company-wide change? Why didn't they continue it if it was superior to other designs?

I decided to have the transmission oil analysis done by Blackstone Labs http://www.blackstone-labs.com/ as I was just interested in seeing what could be learned. I got good news and thought someone might benefit from seeing the report which I will redact and submit again tomorrow. [great point knucklehead] The process was really simple and did not upset my local post office. I found the staff friendly, helpful and informative. Howard
